ArticleA General Framework for the Evaluation of Direct Nonoxidative Methane Conversion Strategies
Context & Scale
Natural gas is a versatile and relatively clean chemical feedstock. The development of natural gas conversion technologies has recently received significant attention due to the increase of natural gas supply in the United States and low natural gas prices relative to crude oil. The conversion of natural gas into chemicals presents a promising means of utilizing an abundant resource while achieving energy security and mitigating pollutant emissions. Yet the direct conversion of methane to olefins is still at the basic research level, and it is unclear which of, and to what extent, these technologies must be improved to develop a commercial process. Toward this goal, we develop a simple yet flexible framework that allows for the systematic evaluation of various process alternatives and the identification of the key technology gaps.
